The bicycle parking lot is implanted into the gazebo, which gives the gazebo parking function without changing the overall structure. The built-in lifting device is added to make the pillar become the main component of the conveying bicycle without changing the shape and function of the pillar. It is set over bridges and roads without affecting the traffic of vehicles and pedestrians, and can beautify the environment.

As shown in FIG. 1, the principle structure of the bicycle parking device 1-7 of the present embodiment is illustrated. The bicycle parking device 1-7 includes:

The lower braced frame 1-2, located on the bicycle parking device 1-7, installs a rotating platform. 2-1,

The rotating platform 2-1 can be rotatably arranged on the lower braced frame 1-2, and a fan-shaped notch 2-7 is placed in the rotating platform 2-1.

The supporting columns 1-1 support the lower braced bracket 1-2. And, at least one rotating column structure 4, which carries the rotating platform 2-1, and the lifting channel 4-9 is provided within the rotating column structure 4, and a lifting device is installed in the lifting channel 4-9, which is detachably connected to the carrier frame used for carrying bicycles. In this embodiment, a rotating column structure 4 is provided as an example. The supporting column 1-1 and rotating column structure 4 may be gazebo columns. The supporting column 1-1 is an ordinary gazebo column, and the rotating column structure 4 is a gazebo column with the lifting channel 4-9 after modification. The support columns 1-3 support an upper supporting frame 1-5 and may include a lifting screw 8-5.

The frame structure of the bicycle parking device 1-7 is shown in FIG. 2. Supporting column 1-1 is used to support an upper support 1-8, which includes upper supporting beam 1-4, upper supporting frame 1-5, support columns 1-3, lower supporting frame 1-2 and lower supporting beam 1-6; The two ends of the fixed rod 2-4 are respectively fixed on upper support beam 1-4 and lower support beam 1-6. The lower support beam 1-6 supports the rotating platform 2-1 through thrust bearing, so that the rotating platform 2-1 can rotate independently on the horizontal plane. A gazebo cover can be added on the upper supporting frame 1-5 to become a gazebo. The gazebo cover can be designed arbitrarily, such as adding solar panels, charging functions and billboards.

As shown in FIG. 3, the structure of the rotating platform 2-1 is indicated. A second motor 2-5, a second driving wheel 2-6 and a platform center wheel 2-3 are arranged on the rotating platform 2-1. The second motor 2-5 is connected with the second driving wheel 2-6, and the second driving wheel 2-6 engages with the platform center wheel 2-3. The second motor 2-5 is fixed on the upper supporting frame 1-5, and the second motor 2-5 drives the second driving wheel 2-6, so as to drive the center wheel 2-3 of the platform 2-3 and the rotating platform 2-1 to rotate together (the platform center wheel 2-3 and the rotating platform 2-1 are fixed as one). The positioning pin 2-2 is distributed on the rotating platform 2-1, and the positioning pin 2-2 is positioned on the carrier frame 6 (the carrier frame 6 has corresponding positioning pin holes).

As shown in FIG. 4, the rotating column structure 4 is shown. The first motor 4-5 drives the first drive wheel 4-4, and the first drive wheel 4-4 meshes with the arc gear ring 4-3. When the first drive wheel 4-4 rotates, the drive arc ring 4-3 drives the second set 4-2 to rotate together (the arc ring 4-3 and the second set 4-2 are fixed together, and the curvature radius of the arc ring 4-3 is the same as the curvature radius of the second set of plates 4-2, as shown in FIG. 5, so that the upper part of the second set of plates 4-2 has meshing teeth. And the meshing teeth on the arc ring 4-3 are located on the outer side. In the non-working state, the rotation of the second set of plates 4-2 makes the vertical opening on the second set of plates 4-2 overlap with the first set of plates 4-6, and the first set of plates 4-6 covers the vertical opening on the second set of plates 4-2 to play a role of safety protection.

The radius of curvature of the first set of plates 4-6 is slightly larger than that of the second set of plates 4-2, and the gap is not exposed when the second set of plates 4-2 are enclosed, which is safer. The width (arc length) of the first set of plates 4-6 is slightly larger than that of the second set of plates 4-2 (arc length). The first set of plates 4-6 and the second set of plates 4-2 are mounted on the thrust bearing 4-1 and rotate mutually on the thrust bearing 4-1.

As shown in attached FIG. 6, the specific structure of the lifting device 8. The lifting device 8 includes the lifting screw 8-5, the lifting guide rail 3-1 and the lifting nut 8-4, shown with the lifting guide rail 3-1 which is vertically set in the lifting channel 4-9. The lifting nut 8-4 can slide connection on the lifting guide rail 3-1. The lifting screw 8-5 spins the lifting nut 8-4. The lifting screw 8-5 rotation drives the lifting nut 8-4 to move up and down along the lifting guide rail 3-1. The carrier frame 6 is detachably connected with the lifting nut 8-4. The lifting device 8 is hidden inside the rotating column structure 4. When working, the lifting motor 7-1 and a tensioning wheel 7-5 drive the lifting belt 7-2 to make the lifting screw 8-5 rotate. During the lifting nut 8-4 action, the lifting nut 8-4 is connected with the electromagnet 8-2. When the electromagnet 8-2 is energized and magnetic, the electromagnet 8-2 engages the carrier frame 6, so that the carrier frame 6 may be lifted. The bicycle 5 may be on the carrier frame 6. The vertical opening width of the second set of plates 4-2 is slightly larger than the size of the electromagnet 8-2.

The structure of the lifting guide 3-1 is shown in FIG. 7. The lifting guide 3-1 is equipped with the positioning slot 3-2 of the lifting guide 3-1.

As shown in FIG. 8, the structure of the lifting nut connecting plate 8-1 is illustrated. Because the lifting nut connecting plate 8-1 is specially designed with the lifting guide rail positioning groove 3-2 on the lifting guide rail 3-1, the lifting nut 8-4 can be lifted smoothly.

As shown in FIG. 9, the status of the bicycle 5 parked on the carrier frame 6 is indicated. The bottom plate of the carrier frame 6 is provided with a front wheel positioning groove 6-3 and a rear wheel positioning groove 6-1, and two wheels 9 of the bicycle 5 are embedded in the front wheel positioning groove 6-3 and the rear wheel positioning groove 6-1 respectively.

As shown in FIG. 10, the carrier frame comprises a bottom plate 6-6 and a back plate 6-4, and a reinforcing plate 6-5 is arranged on both sides of the connection between the bottom plate 6-6 and the back plate 6-4. The front wheel positioning groove 6-3 and a rear wheel positioning groove 6-1 are arranged on the bottom plate 6-6 of the carrier frame 6. A plurality of positioning pins are arranged on the rotating platform 2-1, and the bottom plate 6-6 of the carrier frame is provided with a positioning pin hole 6-2 for insertion of the positioning pin.

The lifting device 8 is driven by the lifting motor 7-1, which drives the tensioning wheel 7-5 to rotate. The lifting belt 7-2 is set on the tensioning wheel 7-5. The lifting belt 7-2 drives the lifting screw 8-5 to rotate, so that the lifting nut 8-4 can be lifted, and the electromagnet 8-2 on the lifting nut 8-4 can adsorb and loosen the carrier frame 6, so that the carrier frame 6 can be lifted, and the rotating platform 2-1 can cooperate with the carrier frame 6.

The shape of carrier frame 6 is the same as the notch shape of rotating platform 2-1, so carrier frame 6 can pass through the notch of rotation platform 2-1. When the carrier frame 6 is higher than the rotating platform 2-1, so that an empty car position on the rotating platform 2-1 reaches directly below the carrier frame 6, the electromagnet power is cut off, and the carrier frame 6 drops to the rotating platform 2-1.

Multiple racks 6 (bikes may or may not be parked on racks 6) are placed on the rotating platform 2-1. Detailed action breakdown is as follows:

If one needs to take the rack 6 from the rotating platform 2-1, complete the following actions: The first motor works 4-5 to rotate the vertical open door 4-8 of the second set of plates 4-2 to the working (open) position. The lifting motor 7-1 motivates the lifting nut 8-4 rise to the set position. The rotating platform 2-1 is rotated so that the carrier frame 6 for the bicycle 5 to be collected is rotated to the gap facing the second set of plates 4-2; The electromagnet 8-2 will be electrified and the carrier frame 6 will be engaged. The lifting nut 8-4 will engage the carrier frame 6 and then continue to raise the set height (about the height of a bicycle, higher than all carrier frames 6 and the highest bicycle height on the rotating platform 2-1). The rotating platform 2-1 rotates and makes the gap on rotating platform 2-1 reach directly below the vehicle 6 to be taken. At this time, the lifting motor 7-1 motivates the lifting nut 8-4, so that the carrier frame 6 is dropped down to the ground, completing the pick-up action. The second set of plates 4-2 may be rotated to open the rotating column structure 4.

The action mentioned above is reversed when storing bicycles 5. The empty frame 6 is motivated to the ground. The person places the bicycle 5 on the frame 6, then the frame 6 rises to the set position, and the rotating platform 2-1 rotates, so that the empty space on the rotating platform 2-1 is positioned below the frame 6, and the frame 6 is lowered to the rotating platform 2-1. The electromagnet 8-2 is powered off and the storage operation is completed.

When the bicycle 5 is not accessed, the carrier frame 6 can also rise to the level of the fan-shaped notch 2-7 with the rotating platform 2-1. Looking up from the bottom of the bicycle parking device 1-7, the carrier frame 6 and the rotating platform 2-1 are closed to form a complete disc. The shape of carrier frame 6 coincides with the fan-shaped notch 2-7 of rotating platform 2-1. There is a gap between rotating platform 2-1 and lower support frame 1-2, which does not affect the normal lift of electromagnet 8-2.

The driving motors are stepper motors, and the position can be precisely controlled. At the same time, various position sensors are added to ensure accurate transmission time and position control. For beauty's sake, the multiple columns 4/1-1 of the gazebo may be designed to look the same. A touch screen and/or LCD advertising may be disposed on the columns 4/1-1.

Each motor and driving mechanism of the invention is controlled by a controller, and corresponding sensors are set for detecting position, stroke and other information.

Although the embodiments are described and elaborated separately above, some common technologies are involved, and it seems to ordinary technicians in the field that they can be replaced and integrated between embodiments, referring to another embodiments that are not explicitly documented in one of the embodiments.
